Application December 11, 1947, Serial No. 790,955

The present invention relates to forks such as may be used in apractical and satisfactory manner on levelling and grading blades usedon tractors, so called bulldozers, and the like.

In reducing to practice the principles of the instant invention, I havefound it expedient and practical to merely attach simple brackets orforks to the tractor blade and to employ said forks for load-carryingand other transportation accomplishments.

More explicitly, an object of the present invention is to provide two ormore L-shaped brackets having attaching hooks. whereby same may bereadily suspended on the upper edge portion of the tractor blade, thehorizontal portions thereof then proecting in advance of the blade andservingto accommodate planks or thelike which are used in building atemporary platform on and in conjunction with the blade for purposes ofconveniently supporting and transporting drums power shovels, aircompressors, and so on and so forth.

Briefly, each bracket or fork is of sectional construction and onesection is of L-shaped form and the other section in the nature of ahook, coacting portions of the two sections being adjustably boltedtogether to enable said brackets to be satisfactorily suspended andemployed on tractor blades of varying widths.

Other objects and advantages of the invention will become more readilyapparent from the following description and the accompanyingillustrative drawings.

In the drawings:

Figure 1 is a side elevational view of a tractor or bulldozer showingone of the fork attachments on a stock-type surface levelling andgrading blade.

Figure 2 is a front view taken on theapproximate line 2-2 of Figure 1,looking in the direction of the arrows.

Figure 3 is a perspective view showing a pair of the brackets in use andshowing the blade in phantom or dotted lines.

Reference is had now to Figure 1 wherein the tractor, as an overallstructure, is denoted by the 2 Claims. (Cl. 214-131) of fuel oil andsupplies to such equipment as is denoted by the numeral 8 and this has ahorizontal limb 9 and a substantially vertically disposable limb III,the latter having bolt holes H to accommodate boltsl2, the bolts l2fitting into bolt holes I3 in the shank or limb portion M of the upperor hook section IS. The hook of the latter, denoted at I 6, is shaped totake over and hang on the upper edge portion of the blade I. It followsthat the sections are adjustably bolted so that the hook l6 engages overthe upper edge and the heel of the L-section 8 rests against the cuttingor lower edge of said blade.

It is obvious that by hanging two or more of these fixtures on thetractor blade, they, in conjunction with the blade, serve to accommodateboards, planks, or the like in building a temporary platform, theplatform being raisable and lowerable in conjunction with the blade andalso being adaptedv to serve as a simple and practical carrier for loadsof varying types on any construction job, railroad, highway, and thelike. In and around farms, much miscellaneous equipment has to betransported, and instead of using trucks, these simple attachments makeit possible to carry the equipment (pumps, drills, tools, etc.) on thetractor as the tractor is moved to the place where the work is to beperformed.

It is believed novel in this line of endeavor to take advantage of thereadily available blade on numeral 5, the same having liftable andlowerable adjustably mounted arms 6 carrying at their forward ends theaforementioned work blade 1. 1t is to the latter that the attachmentsare detachably connected. Each attachment is a'fixture or bracket andboth are the same, and the description of one will sumce for all. Tothis end, the main L-shaped portion or section of the bracket a tractoror bulldozer and to apply thereto simple adjustable brackets orfixtures, the latter of such construction that they may be utilized forload handling and transporting purposes.

In view of the foregoing description taken in con-'unction with theaccompanying drawings, it

is believed that a clear understanding of the device will be quiteapparent to those skilledin this art. \A more detailed description isaccordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a-preferred embodiment of the invention, the same issusceptible to certain changes fully comprehended by'the spirit of theinvention as herein described and within the scope of the appendedclaims.

Having described the invention, what is claimed as new is:

1. In a structure of the class described, in combination, a tractorincluding a transverse vertically adjustable blade of a conventionalbulldozer type. a pair of duplicated longitudinally spaced brackets,said brackets being removably hung on and attached to and extendingacross the concaved advance surface of said blade, each bracketcomprising an L-shaped section whose heel por- 3 tion rests upon theusual lower cutting edge of said blade, whose horizontal limb projectsforwardly beyond said blade and whose remaining limb partially spans theconcaved surface 01 said blade, a

hook engageable over the upper edge 01' said blade, said hook having adepending shank overlapping the vertical limb of said L-shaped section,said shank being adjustably and detachablyconnected' with said limb.

2. A plank hanging and supporting attachment for a conventional-typetractor blade comprising an L-shaped section whose heel portion isadapted to rest on the cutting edge of said tractor blade,

whose horizontal limb is adapted to project forwardly beyond said bladeand whose remaining limb is adapted to rise in vertical spaced relationin advance oi! the usual blade, and a hook engageable over the dishedfront surface of the upper edge of the tractor blade, said hook having ashank portion and said shank portion being detachably connected withsaid L-shaped section.
